[0002] In the production process of LCD screens, it is usually necessary to perform laser cutting on the LCD screen panels. For example, it is necessary to cut the corners of a small square panel so that the four corners of the display panel have a certain curvature. Currently, the commonly used display panel cutting methods are CNC cutting and laser cutting. Laser cutting has gradually become the mainstream process in the industry due to its high efficiency.
[0003] When laser cutting is performed, the display panel needs to be limited by a laser cutting stage, and the laser cutting transmitter is located at the top of the display panel. The laser cutting transmitter emits a laser with a certain cutting ability to cut the four corners of the square panel along the cutting path. However, when the laser penetrates the display panel and reaches the plane of the laser cutting stage, since the stage is not an absolute plane, it will cause reflected lasers at different angles, thereby burning the internal wiring of the display panel within the range of the reflected light near the cutting track, thereby damaging the display panel.

BRIEF DESCRIPTION OF THE DRAWINGS
[0018] In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the drawings required for use in the embodiments are briefly introduced below.
[0019] Figure 1 is a schematic diagram of laser reflection;
[0020] Figure 2 This is a schematic diagram of the structure of a display panel laser cutting stage in one embodiment of the utility model;
[0021] Figure 3 for Figure 1 A schematic structural diagram of a positioning stage body of a display panel laser cutting stage;
[0022] Figure 4This is a schematic structural diagram of a display panel laser cutting stage in another embodiment of the present invention; DETAILED DESCRIPTION
[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.
[0024] See also Figure 2 or Figure 3 As shown, a display panel laser cutting platform 10 includes: a positioning platform body 100 and a display panel 200, the positioning platform body 100 is provided with a plurality of vacuum adsorption holes 110; the display panel 200 has a cutting portion 210, when the display panel 200 is placed on the positioning platform body 100, each vacuum adsorption hole 110 is used to adsorb and fix the display panel 200; and an anti-reflection structure is provided on the positioning platform body 100, the anti-reflection structure corresponds to the cutting portion, when the cutting portion on the display panel is laser cut, each anti-reflection structure is used to prevent laser reflection.
[0025] It should be noted that if Figure 1 As shown, it is a schematic diagram of laser reflection. The laser is incident from the cutting part, which is the incident light a. It is reflected by the surface of the positioning stage body 100, which is the reflected light b. The reflected light b is reflected back to the wiring area c of the display panel 200, causing damage to the wiring area, thereby reducing the yield rate of the product. Therefore, in the utility model, an anti-reflection structure is provided on the positioning stage body 100, and the anti-reflection structure corresponds to the cutting part. When the laser cuts the cutting part on the display panel, the anti-reflection structure prevents the reflection of the laser, thereby preventing the laser from damaging the wiring on the display panel 200.
[0026] See also Figure 2 and Figure 3As shown, in one embodiment, the anti-reflection structure is an anti-reflection hollow portion 120, and the positioning stage body 100 is hollowed out to form the anti-reflection hollow portion 120, and the anti-reflection hollow portion corresponds to the cutting portion. Then during laser cutting, the laser loses the reflection interface and will be directly projected. In this way, there will be no problem of laser reflection damaging the internal wiring of the display panel. Furthermore, the display panel 200 has a plurality of cutting portions 210, and a plurality of anti-reflection hollow portions are also provided, each anti-reflection hollow portion corresponds to each cutting portion, and the anti-reflection hollow portion is used to prevent laser reflection from damaging the internal wiring of the display panel. For example, the cutting portion 210 on the display panel includes four corner cutting portions 211, and the anti-reflection structure is provided at four locations, and each anti-reflection structure corresponds to the four corner cutting portions 211 respectively. The four corner cutting portions 211 mean that the four corners on the display panel need to be cut in an arc, so the positioning platform body 100 corresponding to these four corners needs to be hollowed out to form an anti-reflection hollow portion 120 to avoid laser reflection; further, the cutting portion also includes a water drop position cutting portion 212, and the anti-reflection structure is provided at five locations, and each anti-reflection structure corresponds to the water drop position cutting portion 212 and the four corner cutting portions 211 respectively, that is, the water drop position cutting portion 212 also needs to be hollowed out to form an anti-reflection hollow portion to avoid light reflection. It should also be noted that the anti-reflection hollow portion corresponding to the water drop position cutting portion 212 is symmetrically arranged, so that the laser transmitter head and the display panel can be placed in two directions.
[0027] See also Figure 4 As shown, in another embodiment, the anti-reflection structure is a light absorbing layer, and the light absorbing layer is disposed on one side of the positioning stage body facing the display panel, and the light absorbing layer corresponds to the cutting portion. That is, a light absorbing layer is coated in the area corresponding to the cutting portion, and the laser light is absorbed by the light absorbing layer so that the light does not form a reflection. For example, the light absorbing layer can adopt an AG anti-glare layer, that is, a material that can interfere with and absorb reflected light, thereby avoiding the generation of reflected light. In this embodiment, the cutting portion includes a four-corner cutting portion and a water droplet position cutting portion, and the anti-reflection structure is disposed in five locations, and each anti-reflection structure corresponds to the water droplet position cutting portion and the four-corner cutting portion, that is, a light absorbing layer is coated in the area corresponding to the water droplet position cutting portion and the four-corner cutting portion, thereby absorbing the laser and avoiding laser reflection from damaging the display panel; in another embodiment, the light absorbing layer can also be directly disposed on the entire surface of the side of the positioning stage body facing the display panel.
[0028] Preferably, the vacuum adsorption holes are circular in structure. After the positioning stage body is evacuated, the vacuum adsorption holes adsorb and fix the display panel to prevent the display panel from shifting. Preferably, the vacuum adsorption holes are distributed in a rectangular array to ensure the stability of adsorption at each position of the display panel.
[0029] In one embodiment, the width of the positioning stage body 100 is greater than the width of the display panel, so that the positioning stage body 100 can better support the display panel.
[0030] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
